Online virus checker

The online virus checker analyzes an input file or a target URL to detect potential malware indicators. It combines heuristic behavior analysis with signature matching against a frequently updated malware database. This enables rapid triage without requiring a full antivirus deployment. The tool is designed for security teams, developers, and IT admins who need quick risk signals before processing or distributing content. It provides a structured risk score, a verdict, and a list of detected threats to guide remediation decisions.
Conceptually, the workflow involves ingesting the source (file or URL), running lightweight analyses, and synthesizing results into a concise risk assessment. Heuristic checks look for suspicious patterns in file structure or URL behavior, while signature matches identify known threats. An optional deep_scan and engine selector allow advanced users to adjust sensitivity and detection scope. Outputs are designed to be machine-readable for automated workflows and human-readable for rapid decision-making. Unique value lies in its combination of speed, up-to-date detection databases, and output formats suitable for security tooling pipelines.
Typical use cases include pre-release file inspection, safe sharing of external resources, and CI/CD pipelines where dependencies or artifacts must be screened before integration. For individuals, it offers a straightforward risk signal before opening an attachment or visiting a link. The tool is free to use and complements existing security suites by providing a fast triage check.
